SPECIFICATION forming part of' Letters-Patent No. 364,095. dated Mayl, 'l 887.

Application filed March 21, 1887.

yTo @ZZ whom it may concern:

Be it known that I, EDWIN E. EDDINGTQN, a citizen of the United States, and a resident of Janesville, in the county of Rock and State of Wisconsin,have invented certain new and useful Improvements in Gulti'vators; and I do hereby declare that the following is a`full,'clear, and exact description of the invention, which will enable others skilled in the artto which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this speeitcatiomand in which- Figure 1 isa side view of my improved cultivator. Fig. 2 is a front view of the same.

' Fig. -3 is a rear view. Fig. is a longitudinal vertical sectional view. Fig. 5 is a top plan view; and Fig. 6 is a perspective view of the shoe at the lower end of the standardsand of the shovel or blade, showing the blade removed and placed at the side of the shoe.

Similar numerals of reference indicate corresponding parts in all the figures.

My invention has relation to thatelass of straddle-row cultivators in which the cultivater-beams are pivotally connected to the forward end of the wheeled frame, and may be guided by the feet of the driver; and it consists in the improved construction and combination of parts of such a cultivator, as her'einafter more fully described and claimed.

In the' accompanying drawings, the numeral 1 indicates thestraight central portion of the axle, the ends of which are formed with longitudinal slots 2, in which slide bolts 3, pro- .lecting from the horizontal portions t of the arched 0r bent outer axle portions, 5, the'said horizontal portions having flanges 6, bearing against the upper and lower edges of the slotted axle portion, and having bolts 7,remov ably inserted in registering perforations 8 in their inner ends and in the central portion inside of the slots. The wheels 9 are journaled upon the spindles of these adjustable axle portions, the portions being adjustable, so as to fit the .cultivator for rows of different widths.

The side pieces, 10, ofthe wheeled frame have their rear ends secured to the axle, and have downwardly-projecting arms 11 at their forward ends, which arms register with similar arms, 12projecting downward from the Serial No. 231,720. v (No model.)

forward arms of a cross-har, 18, secured with its arms to the side pieces, and the forward ends of the side pieces and of the armsof this cross piece or bar are connected .by means of a forward cross piece, 14. The tongue 15 is secured to the middle of this forward end piece or cross-piece, and with its inner end in the` center of t-he other cross piece or bar. v 6o Arms 16 are pivotedwith their lower ends between the lower ends of the downwardlybent arms of the frame,` and the lower portions ot' these pivoted arms are provided each with two rearwardly extending eyes, 1 7, 65 through which bolts 18 pass. The upper ends of the arms are slightly curved rearward, and are formed with eyes 19 at their upper ends, and the forward reduced ends of rods 20 slide within these eyes, while the rear ends ofthe 7o rods are pivoted to the lower arms of two levers,l 21, fulcrumed upon the inner sides of the side pieces of the frame, and having sharp edges or flanges 22 upon the outer sides of the upper arms, with. which they engage in-l wardly-bent serrated and' segmental flanges 23 upon segmental plates or castings 24 upon the lside pieces concentric to the levers.

' The eyes 25, formed in the forward bifurcated ends of a bar, 26, and a brace-rod, 27, are piv- 8o oted upon each bolt in the eyes of the pivoted arms, and the rear ends of the bars are bifurcated, as shown at 28, and have the forward' ends of the beams 29 pivoted between them upon vertical bolts 30. these beams are formed with inwardly-bent curved tongues 31, through which pass hooked screw-bolts 32, having the hooked ends upon the concave sides of the tongues, and these curved lips and hooked bolts form a bearing 9o or fastening for the upper ends of the forward standards, 33, the screw-bolts having nuts 34 for drawing them to clamp the standards upon their outer ends. vThe rear ends of the'beams are provided with outwardly-bent tongues 35 V95 of a similar shape, having hooked bolts 36, and securing the upper ends of the rear standards, 37. I

A transverse bar, 38, is formed with socketsl or sleeves 39 at its ends, and these sockets or Ico sleeves have "setscrews 40 inserted through them,which bear with their inner ends against v the inwardly-bent ends 41 of arms 42, having the lower ends of their vertical portions bi- 'Iheforward ends of 85 A furcated to form forwardly-inclined arms 43, having vertical ends 44, provided with heads 45 at their lower ends, and sliding in eyes 46 upon the outer sides of the beams, and rearwardly-inclined arms 47, formed with eyes 48 at their ends, pivoted in eyes 49 upon the beams.

'.lhe tongues at the forward and rear ends of the beams are pivoted at their bent portions to the sides of the beams upon bolts 50, and the rear and forward ends, respectively, of the forward and rear tongues are formed with vertical slots 5l, with which they slide adj ustably upon nutted bolts 52 in the beams, the tongues rocking upon the pivotal bolts,so that the standards may be adjusted at different angles to the beams and to the surface of the ground, as desired.

Semi-cylindrical shoes 53 are secured to the' lower ends of the standards by means of nutted bolts 54 passing through them, and the lower ends of these shoes are formed with circular plates or rosettes 55, having radiating serrations upon their forward faces, and having nutted bolts 56 passing through their centers, and the rear faces of the blades 57, which are of the same construction as the blades shown and described in my former patent, No.

347,588, granted to me on the 17th day ofAugust, 1886, are formedwith registering and corresponding` radiating serrations, 58, and with perforations 59 for the bolts, so that the blades may be adjusted to the serrated plates of the shoes in any desired position, the serrations holding them in their adjusted positions when the bolt has been tightened. l

It will be seen that the axle maybe adj usted to bring the wheels to register with rows of different width by sliding the spindle portions out or in with their slotted and ianged por` tions, and it will be seen that the beams may be'adjusted. closer `to each other or farther The beams may be separately raised or lowered by means of their respective hand-levers,

and the angles ofthe standards may be adj usted and desire to secure by Letters Patent of the y United States- 1. In a straddle-row wheelcultivator, the I 'combination of a wheeled frame having two pai rs of do wnwardly-projecting arms at the forward ends of its side pieces, arms pivoted with their lower ends between the lower ends of the pairs of arms and having each two rearwardlyextending ears, and having their'upper ends curved slightly rearward and formed into eyes at the ends, bars having the beams pivoted to their rear ends and having their bifurcated eyed ends and the bifurcated eyed ends of brace-rods pivoted to the ears of the arms upon bolts', hand-levers pivoted upon the frame and having means for holding them adjusted, and rods pivoted to the ends of the levers and having their reduced forward ends sliding in the eyed upper ends of the pivoted arms, as and for the purpose shown and set forth.

2. In a straddle-row wheeled cultivator, the combination of a wheeled frame, two beams having standards and having their forward ends supported by bars provided with means for raising and lowering them, a cross-bar formed with sleeves or sockets at its ends, having set-screws in their sides, and bars having their upper horizontal portions secured adjust-ably in the sleeves or sockets, and having their vertical portions formed into forwardlyinclined arms having vertical ends sliding in eyes upon the beams and into'rearwardly-nclined arms pivoted with eyes to eyes upon the beams, as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.
